You need to name your URLs: https://docs.djangoproject.com/es/1.9/topics/http/urls/#naming-url-patterns
urlpatterns = [ url(r'^doll/$', views.doll_describer), url(r'^yourdolldata/(?P<id>\d+)/$', views.yourDollData, name='yourDollData' ), url(r'^connexion/$', views.connexion), url(r'^logout/$', views.deconnexion), ] From: "Luigi Mognetti" <luigimogne...@gmail.com> To: "Django users" <django-users@googlegroups.com> Sent: Tuesday, April 5, 2016 12:17:39 PM Subject: url redirect with kwargs no NoReverseMatch http://stackoverflow.com/questions/36411798/url-redirect-with-kwargs-no-noreversematch main-project urls.py : from django . conf . urls import include , url from django . contrib import admin urlpatterns = [ url ( r '^admin/' , include ( admin . site . urls )), url ( r '' , include ( 'data.urls' )), ] urls.py : (from the data_app) urlpatterns = [ url ( r '^doll/$' , views . doll_describer ), url ( r '^yourdolldata/(?P<id>\d+)/$' , views . yourDollData ), url ( r '^connexion/$' , views . connexion ), url ( r '^logout/$' , views . deconnexion ), ] views.py def doll_describer ( request ): # if this is a POST request we need to process the form data if request . method == 'POST' : # create a form instance and populate it with data from the request: form = DollForm ( request . POST ) print ( form ) # check whether it's valid: if form . is_valid (): print ( "was valid" ) doll = form . save ( commit = False ) doll . save () print ( "DOG.ID=" , doll . id ) return HttpResponseRedirect ( reverse ( 'yourDollData' , kwargs ={ 'id' : doll . id })) else : print ( "form is not valid" ) # if a GET (or any other method) we'll create a blank form else : form = DollForm () print ( "wasn't valid" ) return render ( request , 'data/doll.html' , { 'form' : DollForm }) def yourDollData ( request , id ): doll = DollData . objects . get ( id = id ) print ( "Doll=" , doll ) print ( "DOG_TYPE=" , type ( doll )) return render ( request , 'data/save.html' , { 'doll' : doll }) I can 't understand why i' m getting the following error : > NoReverseMatch at /doll/ And it concerns the `HttpResponseRedirect(reverse('yourDollData', kwargs={'id': doll.id}))` Tough, everything's fine with the `doll.id` which is printed out correctly one line before. Of course when I hard access in my browser to 127.0.0.1:8000/yourdolldata/15/ it works perfectly. So it's all about this reversing process. I guess it has something to do with my url regex not matching what I think I'm reversing ... How can i get that fixed ? I know it's a common mistake but I can't see any thing done the wrong way after I've done my internet research. -- You received this message because you are subscribed to the Google Groups "Django users" group.
